Head and neck squamous cell carcinoma (HNSCC) is a common type of cancer worldwide. Strong connections have been revealed between immune cells and the pathogenesis of HNSCC. Important differences regarding the levels of immune cell subpopulations in both peripheral circulation and tumor microenvironment were emphasized, with some of them having prognostic significance. In our study, we performed an analysis of immune changes in the tumor tissue and the peripheral blood of untreated HNSCC patients, investigating the proportions of different immune cell populations in these two compartments. The local infiltrating lymphocytes were mainly cytotoxic T cells (CD8+). We have also revealed an increased level of B lymphocytes (CD19+) in the tumor microenvironment. In peripheral blood, the most important lymphocyte subtype was represented by the helper T lymphocytes (CD4+). We also found an increased proportion of circulating NK cells (CD56+). Our results showed significant differences betwe...

This study was performed to determine whether peripheral blood (PB) monocyte and/or lymphocyte activation at diagnosis were associated with long-term prognosis in patients with head and neck squamous cell carcinoma (HNSCC), and to what extent such prognostic properties relate to human papilloma virus (HPV)-associated tumor infection of the included patients. This was a long-term prospective study describing patient survival in relation to PB T lymphocyte and monocyte activation in patients observed for up to 14 years following diagnosis. Sixty-four patients from a consecutive cohort of newly diagnosed HNSCC patients along with 16 non-cancer control patients were included over a period of almost 2 years. Monocyte responsiveness was assessed at diagnosis (N = 56 HNSCC/16 non-cancer controls) by measuring net levels of spontaneous vs lipopolysaccharide-induced monocyte chemotactic protein (MCP)-1 secretion in vitro. PB T lymphocyte activation was determined (N = 58 HNSCC/16 controls) b...

Background: Oral squamous cell carcinoma (OSCC) is a common cancer with high morbidity and mortality. Alterations of antitumor immune responses are involved in the development of this malignancy, and investigation of immune changes in the peripheral blood of OSCC patients has aroused the interest of researchers. Methods: In our study, we assessed the proportions of CD3+ total T lymphocytes, CD3+CD4+ helper T lymphocytes, CD3+CD8+ suppressor/cytotoxic T lymphocytes, CD3−CD19+ total B lymphocytes, and CD3−CD16+CD56+ NK cells in the peripheral blood of OSCC patients. Results: The data obtained both pre- and post-therapy showed a similar level of total CD3+ T lymphocytes in OSCC patients and control subjects, pinpointing the stability of this immune parameter. On the other hand, pre-therapeutic data showed a lower proportion of helper T lymphocytes (CD4+), a significantly higher level of cytotoxic/suppressive T lymphocytes (CD8+), and a much lower CD4+ T lymphocyte/CD8+ T lymphocyte rat...
Tumor infiltrating lymphocytes and survival in patients with head and neck squamous cell carcinoma
Head & neck, 2016
Because immune responses within the tumor microenvironment are important predictors of tumor biology, correlations of types of tumor infiltrating lymphocytes (TILs) with clinical outcomes were determined in 278 patients with head and neck squamous cell carcinoma (HNSCC). Infiltrating levels of CD4 (helper T cells), CD8 (cytotoxic/suppressor T cells), FoxP3 (regulatory T cells), CD68 (myeloid-derived suppressor cells,) and CD1a (Langerhans) cells were measured in tissue microarrays (TMAs). Cox models tested associations with patient outcomes after adjusting for all known prognostic factors. Median follow-up was 36.6 months. Higher CD4 and CD8 TIL levels were associated with improved overall survival (OS; hazard ratio [HR] = 0.77; 95% confidence interval [CI] = 0.65-0.93; p = .005 and HR = 0.77; 95% CI = 0.64-0.94; p = .008, respectively), and relapse-free survival (RFS; p = .03 and .05, respectively). After controlling for prognostic factors, higher CD4 levels predicted improved OS ...

Background: Leukocytes in peripheral blood (PB) are prognostic biomarkers in head and neck squamous cell carcinoma cancer patients (HNSCC-CPs), but differences between HNSCC-CPs and healthy adults (HAs) are insufficiently described. Methods: 10-color flow cytometry (FCM) was used for in-depth immunophenotyping of PB samples of 963 HAs and 101 therapy-naïve HNSCC-CPs. Absolute (AbsCC) and relative cell counts (RelCC) of leukocyte subsets were determined. A training cohort (TC) of 43 HNSCC-CPs and 43 HAs, propensity score (PS)-matched according to age, sex, alcohol, and smoking, was used to develop a score consecutively approved in a validation cohort (VC). Results: Differences in AbsCC were detected in leukocyte subsets (p < 0.001), but had low power in discriminating HNSCC-CPs and HAs. Consequently, RelCC of nine leukocyte subsets in the TC were used to calculate 36 ratios; receiver operating characteristic (ROC) curves defined optimum cut-off values. Binary classified data were ...

Aim: To assess the prognostic value of hematologic markers for cancers of the head and neck region, according to tumor site. Methods: We reviewed the data of 441 patients diagnosed with head and neck squamous cell carcinomas (HNSCC) between 2006 and 2014. Overall survival rates were estimated using the Kaplan-Meier method and Cox proportional hazards models were used to assess the hazard ratio (HR) for death, according to hematologic markers. Results: In the univariate analyses, hemoglobin concentration; leukocyte, neutrophil, monocyte, and platelet counts; and the platelet-lymphocyte ratio were associated with overall survival. In the multivariate analyses, hemoglobin concentration (HR 0.55, 95% confidence interval [CI] 0.38-0.78, p < 0.001) and leukocyte (HR 1.57, 95% CI 1.11-2.23, p = 0.010), monocyte (HR 1.86, 95% CI 1.25-2.73, p = 0.003), and platelet (HR 2.17, 95% CI 1.24-3.57, p = 0.008) counts were independent prognostic factors for HNSCC. None of the hematologic markers were significant prognosticators for oral cancer. Leukocyte (HR 2.67, 95% CI 1.17-6.58, p = 0.018), monocyte (HR 4.04, 95%CI 1.85-8.56, p < 0.001), and platelet (HR 3.77, 95% CI 1.55-8.28, p = 0.005) counts were independent prognostic factors for laryngeal cancer. Conclusions: Several hematologic markers have prognostic significance for patients with HNSCC, however, the magnitude of the effect depends on the tumor site.

IMPORTANCE Given the role of inflammation in cancer progression, neutrophil-lymphocyte ratio (NLR) from peripheral blood has been suggested as a readout of systemic inflammation and a prognostic marker in several solid malignant neoplasms. However, optimal threshold for NLR in US patients with head and neck cancer remains unclear. OBJECTIVE To evaluate the optimal NLR threshold as a potential prognostic biomarker for survival outcomes. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study was conducted at a single institution. Participants included 496 patients with nonmetastatic head and neck cancer who underwent chemoradiation from April 2007 to March 2021. Statistical analysis was performed from September to December 2021. EXPOSURES High vs low NLR. MAIN OUTCOMES AND MEASURES Overall survival (OS) and cancer-specific survival (CSS). RESULTS A total of 496 patients (411 male patients [82.9%]; 432 White patients [87.1%]; 64 patients with other race or ethnicity [12.9%]; median [IQR] age, 61 [55-67] years) were identified. Median (IQR) follow-up was 44.4 (22.8-74.0) months. Thresholds of NLR for both OS and CSS were 5.71. High NLR above 5.

Background A crucial role for the immune system has been proposed in the establishment and progression of head and neck squamous cell carcinoma (HNSCC). In this study, we investigated the cytokine and regulatory profiles of T cells in tumor draining lymph nodes (TDLNs) of patients with HNSCC. Results The frequencies of CD4+TNF-α+ and CD4+TNF-αhi negatively were associated with poor prognostic factors such as LN involvement (P = 0.015 and P = 0.019, respectively), stage of the disease (P = 0.032 and P = 0.010, respectively) and tumor size (P = 0.026 and P = 0.032, respectively). Frequencies of CD8+IFN-γ+ and CD8+IFN-γ+ TNF-α+ T cells showed negative relationship with tumor grade (P = 0.035 and P = 0.043, respectively). While, the frequencies of CD4+IL-4+, CD8+IL-10+, CD8+IL-4+T cells were higher in advanced stages of the disease (P = 0.042, P = 0.041 and P = 0.030, respectively) and CD4+IFN-γ+TNF-α−, CD8+IL-4+ and CD8+IFN-γ+TNF-α− T cells were higher in patients with larger tumor siz...
Lymphocyte‐Tumor Cell Interaction in Patients with Head and Neck Cancer
The Laryngoscope, 1978
Peripheral lymphocytes from 12 patients with squamous cell carcinoma of the head and neck were incubated with autologous tumor explants. Four of the 12 patients demonstrated lymphocyte induced tumor cytotoxicity. These lymphocytes adhered to the tumor cells and deposited a radioactive label from their surface onto tumor cells. The deposition of this label was associated with tumor death.Tissue sections from those patients who demonstrated lymphocyte cytotoxicity showed a marked plasmacytic infiltration. This was in contrast to non‐responders where only a desmoplastic tissue response was observed with few inflammatory cells.

Background & Objectives: In OSCC, the presence of regional lymph node metastasis at presentation is the most significant adverse prognostic factor and a major determinant of poor survival. Tumor-infiltrating lymphocytes (TILs) often infiltrate solid malignant tumours and extensive lymphocyte infiltration has been related with a more favourable prognosis in patients with various cancers. OSCC often contain large mononuclear cell infiltrates, comprised mainly of T cells, which could reflect an in situ immune reaction against the malignant OSCC cells. The aim of this retrospective study was to evaluate the expression of Cytotoxic T lymphocyte in OSCC using immunohistochemical marker CD8+(CTLs) and correlate these findings with the status of lymphnode. Methods: The study was conducted on tissue sections obtained from histopathologically diagnosed cases of OSCC (n=30) retrieved from the archives of Department of Oral and Maxillofacial Pathology. The sample consisted of cases showing lymph node metastasis (n=15) and those without pathologic lymph node involvement (n=15). The sections were evaluated by using immunohistochemical staining technique with marker CD8 for Cytotoxic T lymphocytes. The mean immunoexpression of Cytotoxic T lymphocyte was evaluated and correlated with lymphnode status. Results: A statistically significant increase in the count of CTLs (CD8+) was observed in lymph node negative pN(-) as compared to lymph node positive cases pN(+) of OSCC. Interpretation & Conclusion: CTLs (CD8+) are involved in modulating the immune response and can contribute to the dissemination or control of metastatic neoplastic cells. It can be considered that T-cell mediated adaptive immunity plays a key role in anti-tumour immunity.
